The amphibious assault ship USS Wasp (LHD 1), along with the transport dock ship USS Green Bay (LPD 20), dock landing ship USS Ashland (LSD 48), and Arleigh Burke class guided missile destroyer USS Shoup (DDG 86), sail alongside the Japan Maritime Self Defense Force (JMSDF) amphibious transport dock ship JS Osumi (LST 4001) during a Passing Exercise (PASSEX) in the Philippine Sea Aug. 26, 2018. PASSEX enabled the Wasp Amphibious Ready Group and the JMSDF a chance to practice communications and maneuvering procedures. The Wasp ARG is currently operating in the region to enhance interoperability with partners and serve as a ready-response force for any type of contingency.
